    Insights

    Fatal prenatal toxoplasmosis in infants is severe due to increased parasite virulence in the fetus. Postmortem studies confirmed Toxoplasma gondii in the central nervous system, liver, and lungs.

    Area of Science:

    • Medical Parasitology
    • Pediatric Pathology
    • Infectious Diseases

    Context:

    • Review of fatal toxoplasmosis cases at Hospital Infantil de México (1943-1973).
    • Inclusion of five postmortem studies identifying Toxoplasma in histologic lesions.
    • Analysis of clinical manifestations including infectious, intracranial hypertensive, neurological, and meningeal pictures.

    Purpose:

    • To review fatal toxoplasmosis cases and associated postmortem findings.
    • To investigate the identification of Toxoplasma gondii in infant tissues.
    • To correlate clinical presentation with neuropathological findings in congenital toxoplasmosis.

    Summary:

    • Toxoplasma gondii was identified within and outside parasitized cells, predominantly in the central nervous system, in all five postmortem cases.
    • Severe fetal disease is hypothesized to result from increased parasite virulence in a second-step infection.
    • Lesion intensity correlated with clinical severity and early postnatal manifestations, with parasites found in the brain, liver, and lungs.

    Impact:

    • Highlights the severe impact of congenital toxoplasmosis on fetal development.
    • Emphasizes the importance of postmortem examination in diagnosing parasitic infections.
    • Provides insights into the pathogenesis of severe fetal toxoplasmosis, suggesting enhanced virulence.

    Teratogenicity01:07

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

    Toxicity Testing in Animals

    Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
    Rocky Mountain Spotted Fever01:26

    Rocky Mountain Spotted Fever

    Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
    Toxoplasmosis01:28

    Toxoplasmosis

    Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

    American Trypanosomiasis

    Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
    Amebiasis01:28

    Amebiasis

    Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
